To address this I just added one additional tab to the spreadsheet — HOT projects ranked by the number of changes made to the map. (This corresponds to the “num_changes” measure in OSM changeset stats.) https://docs.google.com/spreadsheets/d/12TjMDsgPoEQadiUWbpKjotTMYKPo5NY4W7EDipHnE7Y/edit?usp=sharing #MapLesotho (project 599) at the top, with a wide margin...

Re: [HOT] Most "active" HOT projects since March 2014
I just updated the spreadsheet — the user numbers were inflated thanks to a
subtle bug in my code with big consequences… they now more closely track total
participant counts in the HOT tasking manager.
(Many thanks to DaCor and Ciaran Staunton who helped me track this down.)

Re: [HOT] Most "active" HOT projects since March 2014
These heatmaps are interesting. Neis changeset online map shows intensity of mapping only with the outset of the bbox. Such heatmap could show the intensity of contribution in various areas based on the number of objects. To use this functionality for an online map with Openlayers or similar javascript tool, we would surely need to aggregate the data. Otherwise, I dont see with a project like the Ebola outbreak, how we could manage nearly 16 millions objects to represent on the Heatmap.

Re: [HOT] Most "active" HOT projects since March 2014
Hi Martin,
It is uneasy to build a statistic that would reflect the various activities.
Coordination through the Task manager is only one part of the mapping done for
projects. It might be ok a mapathon where you worked only coordinating through
the Task Manager. Aslo, Hashtags are not always added to the changeset comment.
The best way to reflect the contributor activity is to go through the history
and extract changesets corresponding to a bbox closed to the each Task Manager
extent and corresponding to the period of the project. The number of changesets
is also a gross estimate of the contributor efforts. How to compare a
contributor that adds 100 buildings, one changeset for each (we see this often
with new contributors) with a contributor that has a few thousands objects in
one edit.
About the grouping, you have main activities like the Ebola outbreak. At the
same time you can have various mapping projects that contribute to this action.
For example, a missing map party on Ebola, where should we classify it.
Also, the Task Manager represents only one part of contributions. As an
example, for the Ebola outbreak the experienced mappers move around and correct
/ enhance various elements of the map without coordinating through the Tasking
manager.

Hallo all,
Here are two basic rankings of HOT project activity in the last year, based on
map contributions in the past 12 months. Discussion on IRC suggested that this
data might be useful to others, so I’m sharing it with the list.
HOT projects ranked by edit activity from Mar 2014 - Feb 2015 (inclusive):
https://docs.google.com/spreadsheets/d/12TjMDsgPoEQadiUWbpKjotTMYKPo5NY4W7EDipHnE7Y/edit?usp=sharing
The first tab shows a ranking of all tasking manager projects by number of
changesets, the second by number of contributors.
This data is not yet captured by the tasking manager: I’m only looking at
participation that actually resulted in changes on the map. To this purpose I
identify changesets in the OSM edit history that were tagged with a HOT project
id.
I’m curious what other people can read from this data, e.g. whether it matches
your intuitions of popular HOT activities.
Of course these kinds of rankings are of dubious utility — projects are rarely
directly comparable in their scope, and larger activations may be structured in
all kinds of ways. Same goes for changesets as a metric.
Does anyone have good suggestions for how one could meaningfully group the
hundreds of HOT projects? E.g. I could aggregate stats for all
#MissingMaps/#MapLesotho/Ebola Outbreak projects, are there similar tags I
should be looking for? Are these actually meaningful distinctions when looking
at contribution outcomes?
Any requests for other stats? I’d be happy to produce more, provided it’s
feasible. No promises :)

I’m likely undercounting: automated iD changeset comments were only introduced

I’m not identifying earlier contributions that have not been tagged manually.

I also noticed the tag #hotosm-cap103 which is not actually referring to a
